-<span class="application">FindBugs</span> allows several aspects of the analyses it performs to be
-customized. System properties are used to configure these options.
-This chapter describes the configurable analysis options.
-</p><p>
-The analysis options have two main purposes. First, they allow you
-to inform <span class="application">FindBugs</span> about the meaning of methods in your application,
-so that it can produce more accurate results, or produce fewer
-false warnings. Second, they allow you to configure the precision
-of the analysis performed. Reducing analysis precision can save
-memory and analysis time, at the expense of missing some real bugs,
-or producing more false warnings.
-</p><p>
-The analysis options are set using the <span class="command"><strong>-property</strong></span>
-command line option. For example:
-</p><pre class="screen">
-<code class="prompt">$ </code><span class="command"><strong>findbugs -textui -property "cfg.noprune=true" <em class="replaceable"><code>myApp.jar</code></em></strong></span>
-</pre><p>

-<a class="xref" href="analysisprops.html#analysisproptable" title="Table&nbsp;9.1.&nbsp;Configurable Analysis Properties">Table&nbsp;9.1, &#8220;Configurable Analysis Properties&#8221;</a>.

- warnings for cases where the source code does not have a comment
- containing the words "fall" or "nobreak". (An accurate source
